This document discusses different types of inflation. It defines inflation as a general rise in prices over time. Inflation can be categorized based on its degree of control, rate of employment, or causes. The main types discussed are demand-pull inflation, cost-push inflation, and markup inflation. Demand-pull inflation occurs when demand increases faster than supply, leading sellers to raise prices. Cost-push inflation happens when costs of production rise, forcing companies to pass those costs to consumers through higher prices. Markup inflation involves companies and workers increasing prices to maintain profit margins.
